We are also using the May 2020 version and I am getting the error when I create and try to open a template using our tabular server connection, but the error does not occur from an unconnected pbit file. We are trying to create a new template, but I'm hesitant to do so if people will not be able to use it. Anyone have any more info on this error?
@mbahonen - that version is 5 months old, and will be 6 months old when the Oct 2020 desktop launches, and there have been a LOT OF changes in internally to the PBIX/PBIT file format since then to allow working with external tools. If you are on the Report Server and cannot upgrade, consider waiting until this month as the new version for the desktop client will be Oct 2020 as well.
If you are not using Report Server, then you should upgrade to the Sept 2020 version that is already out and try again. Then, if the issue persists, post about it with details in the Issues forum.
Thank you for that feedback, unfortunately our release schedule is far behind and its out of my control. We will likely be using May 2020 for a while. Do you know for sure if this issue has been resolved in later releases?
For us with the update to the June 2020 version, the issue fixed itself. But with the May one, this was a huge problem all through our organization.
Sorry, no, but I've not run across this and this thread kind of died after June, so it suggest to me it was.
I am sure the release schedule is out of your control, but unfortunately Power BI is not like most other apps Microsoft publishes. There is no "Stable Build" cycle like you get with Office for a Deferred Channel. While I would not suggest upgrading the day of a release, usually upgrading 2-3 weeks after a release is the best time for maximum stability as MS publishes many minor fixes each month. But holding on to an arbitrary month isn't good practice.
Even for those using Report Server, which does happen to be May, MS releases many fixes as needed to keep that typical Feb/May/Sept builds as stable as possible for the Report Server users. They do not do that with the normal desktop though. Once June is released, they forget about May. MS today is only concerned with minor patches to Sept, and the Oct pending release, and when that is release, Sept 2020 is in the rear view mirror.
Hello! Did you manage to find a solution to this issue?
We are experiencing the same problem when trying to open ANY template since upgrading to the May 2020 PBI version.
The files are perfectly fine and not corrupted and they open without issues in a previous PBI version.
You'll need to restore from a backup/previous version. It sounds like the file got corrupted. Also, ensure you are using a newer versio of the desktop. You can get odd errors if you open a PBIT/PBIX with older versions of the desktop tool. Normally it says it was created with a newer version, but just in case...
when did you update your Desktop application? try to use previous version of powerbi
